Chapter 1 Before installing Solaris OS
This chapter describes what information should be confirmed before installing Solaris OS.
1.1
How to determine swap size
Swap space size is determined by considering the swap space size requirement of the application and the
physical memory size.
If the system runs out of swap space when the application is in use, the system may terminate abnormally.
Therefore, ensure that you allocate enough swap space to satisfy the demands of all the applications.
The memory image is written once in the swap space listed first in the /etc/vfstab file. If the system crashes,
the memory image in the swap space is copied as a crash dump file under the /var/crash/hostname directory
as the system reboots.
To ensure crash dump files are complete, follow the table to determine the swap space size.

/M8000/M9000
Note:
A greater amount of swap space may be required for the memory image, depending on how the system has
been used at the time of the system crash. If the memory image is larger than the swap size, the crash
dump file cannot be taken. In this case, enlarge the swap space or the device of the crash dump file with
the dumpadm(1M) command. For use of the dumpadm(1M), see the relevant man pages.

How to use DVD drive
When using DVD drive on SPARC Enterprise M8000/M9000 servers, it needs to be set up with the
cfgdevice(8) command of eXtended System Control Facility (XSCF).
For more details, refer to "SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers XSCF
Reference Manual".
